"the "K" cam works well with carbs": This is very true because it has the same seat to seat timing.

Low Compression, closing the lobe centres up a little is helpful.

High Compression, a longer exhaust lobe can be used because high compression & high octane burns faster, so opening the exhaust valve earlier helps overcome the poor exhaust port flow.
